DAVID DALZELL, OF SOUTH EGREMONT, MASSACHUSETTS.

IMPROVEMENT IN AXLE-BOXES.

Specification forming part of Letters Patent No. 175,943, dated April11, 1876; application filed March 24, 1876.

To all whom it may concern Be it known that I, DAVID DALZELL, of SouthEgrcmont, county of Berkshire and State of Massachusetts, have inventeda new and useful Improvement in Axle-Boxes for Carriages; and I herebydeclare that the folstrength and which will not heat and stick,

fast, as when iron or steel is employed.

This trouble and annoyance is entirely obviated in myinvention, andwhich will be readily appreciated by those who have experienced themisfortune of a Wheel sticking fast upon the road, and which occursalmost invariably beyond the reach of facilities for relief. It is alsofound in practice that a comparatively small quantity of oil is requiredin the use of this material, a saving of nearly one-half being effected.

In the modification illustrated in Fig. 3 I have shown an ordinary boxas lined with this material, which will be desirable in applying myinvention to heavy carriages; but for light vehicles this external boxis dispensed with.

The box is secured within the hub in any well-known way-for example, bywedges or an adhesive composition; but I do not confine myself to anyspecial means for efl'ecting this; neither do I confine myself to anyspecial form of box, as it is obvious that the material may be moldedorturncd into any well-known shape for this purpose.

This material is treated in any of the wellknown methods for reducingpaper-pulp and compressing it into form and incorporating any of thewell-known gums, to efi'ect a vulcanization of said material.

- I am aware that it is not new to use prepared paper for this purpose,applied in a particular way, but I am not aware that vulcanized pa perhas heretofore been used.

Having fully described my invention, what I claim, and desire to secureby Letters Patcut, is-

1. As a new article of manufacture, an axlebox made of vulcanized paper,substantially as set forthw 2. An axle ifiade of vulcanized paper, incombination witli an ordinary metal box, said vulcanized-paper box beingarranged within the metal box, as shown and described.
